hey guys, boston mids/highs are on the way but i need to find an amp that will fit under my seat. i have a reg cab w/ buckets and there isn't much room back there. i'm looking for a 4 channel amp like a 40+x 4 but like i said...isn't much room under there. will the alpine 40x4 fit? 's like 9.5x2 5/16x 10 5/8 or something like that? i don't really have my truck right now to measure. otherwise any suggestions?
